Time-place learning in golden shiners (Pisces: Cyprinidae).
The goal of this study was to determine whether fish can learn to forage in different places at different times of the day, each place being associated with a specific time. Groups of eight golden shiners (Notemigonus crysoleucas) were kept in aquaria equipped with automatic feeders that dropped food on one side in the morning and on the other side in the afternoon, or on one side in the mornin...
متن کاملPebble nest microhabitats of Semotilus species (Pisces: Cyprinidae)
The pebble nest microhabitats of four species of Semotilus were compared. Pit/mound nests of Semotilus corporalis were significantly larger than the pit/ridge nests of Semotilus atromaculatus, Semotilus lumbee, and Semotilus thoreauianus. Nests of S. corporalis were in wider and deeper streams. Pits of S. lumbee nests were longest of the four species; those of S. corporalis were widest and deep...
متن کاملAnalysis of vitellogenin gene structure in Caspian roach, Rutilus caspicus (Pisces: Cyprinidae) during exposure to Atrazine
Chemical contamination of aquatic environments to EDCs has become a major focus of environmental toxicology research. The exposure of fishes to estrogenic EDCs in aquatic environments is most frequently assessed by analyzing Vitellogenin (Vg) (the egg yolk precursor protein) expression. Therefore, characterization of Vg gene is of high priority for EDCs bio-monitoring. So, we prepared liver tis...
متن کاملModels for length back-calculation in Caspian Kutum, Rutilus kutum (Pisces: Cyprinidae) from the Caspian Sea
The Caspian Kutum, Rutilus Kutum (Kamensky 1901) specimens were sampled by purse seine in the northern Iranian coast of the Caspian Sea at four locations: Feridoonkenar Shahed, Mahmoudabad Khoram, Lariim Azadi fishing coop, and the Shiroud River in Ramsar city. “Back-calculation” is a retrospective method of estimating the characteristics of growth of fish in terms of length and rate of growth...
